Mistaking Instances for Hymnals

Any chance the program can be trained to distinguish between number of instances and number of hymnals in which those instances occur? Particularly with hymns like "All hail the power of Jesus' name", which are (at least in the USA) very frequently included in hymnals twice or even three times (CORONATION, DIADEM, MILES LANE), the statistical distortion can be quite misleading.
